Summary
Gallbladder cancer is strongly linked to gallstones, especially in patients over 60. Early detection is rare, with incidental findings offering the best survival rates for this aggressive cancer.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Epidemiology
Background:
- Gallbladder carcinoma frequently coexists with gallstones.
- Diagnosis often occurs at advanced stages, leading to poor prognoses.
Purpose of the Study:
- To analyze the association between gallstones and gallbladder cancer.
- To identify risk factors and survival outcomes in gallbladder carcinoma patients.
Main Methods:
- Retrospective analysis of 3119 patients with cholelithiasis and 35 with gallbladder cancer.
- Evaluation of cancer rates, age distribution, stage at diagnosis, and survival.
Main Results:
- 94% of gallbladder cancer cases were associated with gallstones.
- Cancer incidence was 1% in patients with cholelithiasis, increasing significantly in those over 60.
- 88% of cancers were advanced stage; preoperative diagnosis was linked to advanced stages (94%) versus incidental diagnosis (31%).
- Long-term survival (58 months) was observed only in early-stage, incidentally diagnosed cases; advanced cases averaged 9.5 months survival.
Conclusions:
- Gallbladder carcinoma incidence rises with age, particularly over 60.
- Early preoperative diagnosis is challenging; incidental detection in gallstone patients offers better survival.
- Selective cholecystectomy for high-risk gallstone patients (over 55) may improve outcomes.
